The design of a rough mill for the production of interior furntirue parts is used to illustrate a simulation technique for analyzing and evaluating established and proposed sequential production systems. Distributions representing the real-world random characteristics of lumber, equipment feed speeds and delay times are programmed into the simulation. An example is given of how bottlenecks are ...

Abstract The first X-ray source catalog of the Insight-HXMT Galactic Plane (∣ b ∣ < 10°) Scanning Survey (GPSS) is presented based on data accumulated from 2017 June to 2021 August. 4 yr limit sensitivities at main energy bands can reach 8.2 × 10 −12 erg s −1 cm 2 (2−6 keV), 4.21 −11 (7−40 and 2.78 (25−100 keV). More than 1300 sources have been monitored a wide band (1−100 which 223 signal-t...

The navigation of small unmanned aerial vehicles (UAVs) mainly depends on global positioning systems (GPSs). However, GPSs are vulnerable to attack by spoofing, which causes the UAVs lose their ability. To address this issue, we propose a deep learning method detect spoofing GPS signals received UAVs. Firstly, describe signal dataset acquisition and preprocessing methods; these include hardware...
